Wouldn't be a good idea for you to accept relevant questions on a separate section of this site directly? Something like "Chemist answers"? This would be my first question: "Can Chromatography help in any way FISH ( Fluorescence microscopy)? If yes, how?" Priyadarshan I see you answered a question from Yahoo Answers.

This would be my first question: “Can Chromatography help in any way FISH ( Fluorescence microscopy)? If yes, how?”

How GC is used in forensics will probably require a separate article that I might do later. You can also test blood for fatty acids (lipids) on GC with Mass Spectrometer detector, a so-called GC/MS. Technically speaking, human plasma is not different from any another sample so you can test blood for any organic matter on GC. Savyasachi,

Try to get your hands on a lot of instrumentations and hopefully the place has some really nice new machines :) After graduation I did the same thing. I liked so many things in Chemistry that I was not ready to commit myself to a very narrow field while in grad school. So I decided to work in the industry for a year, but ended up working for almost 3 years before I was able to go back to school. It is very easy to get sucked in, you start making money and then it is very hard to go back to be a poor grad student :) doing TA or something. man, my poor blog got hammered today, or as they say "slashdoted". I've had almost 7000 people come so far. I am glad it survived the people surge - 10 requests per sec is no joke. I see.

I hope naisy428 will read your comment and visits the forum with his/her analytical chemistry questions. Mitch,

But I thought you have not decided where you wanna go after graduation. Ψ*Ψ,

Hopefully they will stick me with the PAH analysis. GC/MS will likely be my life after graduation. Hopefully they will stick me with the PAH analysis.
